The calculation of the astronomical unit can be very difficult depending on the calculation methodology chosen.

We decided to propose to our readers a file writen by Mr Arkan Simaan for the Physics Education journal http://www.iop.org/journals/physed and a file written by Mr Robin Catchpole for the same journal.
